<input id="uauy4"></input> Jinyuan District at the junction with Qingxu County Qingyuan Town Village, the surrounding area was once known for paddy area. The passage of time, the village's water flowing within the river has been replaced by Blackwater, paddy had disappeared, replaced by the village and the village side stacked dark coal. Hard to imagine that there was once a lofty and peaceful world. "Silent water into the rice fields," the mood has become memories, but see the shuttle bulldozers rumbling in the coals, the small village of paved road was full of coal face. This is the October 21 "and state environmental line" reporter interview team set foot on this land to see the sights.
Due to coal and Xing, because coal and sleepy. In the context of the coal market downturn, many villages Taiyuan not rich, dirt and even the Green Wave waves of idyllic gradually disappearing. According to reports, on the north east of the village for a large area of coal storage site, Jinyuan District, local villagers armed farms leased land, built a two and three coal washery storage field, about 40,000 tons of coal storage. Among them, a lot of low quality coal or coal gangue. After being "green line and the state" exposure, the local government carried out emergency treatment of stored coal - in dealing with these coal, the easiest way is the "in situ digestion", bulldozed, compacted and then covered become common practice , as long as no dust pollution on it.
The number of low-quality coal or coal waste in the end within Taiyuan villages? "And the state environmental protection line" reporter interviewed journalists at the ancient cross, Gujiao city government official said, self-built mine (Gujiao originally for Gujiao mining area) since, the city has produced a total of more than 5000 tons of coal waste, has there are more than 3000 tons of coal waste is processed, to be treated more than 2000 tons, the vast majority of non-primary gangue. Damaged wall of wind and dust, from afar the yard was full of "Coal" ...... October 15, "and the state Environmental Protection OK" Reporter journalists in Gujiao thorough investigation, the thought found an illegal coal yard sale reserve but into the yard, only to find the yard is full of gangue. Gujiao City law enforcement officers accompanying the EPA said: "This courtyard in the ancient cross is not the main gangue more how to deal with the municipal government to become the most intractable problems.."
Glorious era in the coal industry, coal gangue is also valuable - these and more are braced coal gangue, and was sent to the plant, as long as the calorific value of coal plants can reach 5,000 calories. In the coal kept Shangcuan few years ago, some have been filled ditch gangue even have been dug out. However, with the rapid decline in coal prices, many opportunists in the village, for being such a worthless gangue "commodity" stuck while on foot. The accumulation of a large number of coal waste in the village how to deal with, but plagued by the local government. "Now processing one ton of coal gangue, count manpower, machinery, and transportation costs, the market price was 100 yuan." Yao Jinyuan District towns a staff, "and these gangue, give away who you are, people are not, Not to mention how much to sell. "
Landfill is the gangue easiest way to deal with minimum cost. However, coal gangue cluttered contaminate groundwater, to find the right ditch legal landfill is not easy. Because, waste rock and seepage ditch deal to do flood control design, and meet the requirements of the ditch most are mine supporting the project. "We have looked east to the town and other places of mine, hoping to help the county consumptive mine waste rock county, but these mines have said is all in accordance with the mine waste rock groove design capacity, and to eliminate a large number of coal gangue is not reality . "Qingxu County Environmental Protection Bureau official said. More seriously, the number of the city's coal gangue is still increasing. According to statistics, there are washing Qingxu County Coal 64, the normal production of about 10, about 5 million tons per year coal washing, coal washing elected annually still is not a small number. Gujiao maintain production status of the number of wash coal preparation plant, and quite Qingxu County, the annual amount of wash coal gangue and Qingxu County elected comparable.
At present, the domestic use of coal gangue papermaking technology has matured, and in situ introduction. However, the use of coal gangue paper, the higher the cost, the market outlook is not good, coal and paper companies rely more on government subsidies to live. Existing domestic enterprises to develop another use of coal gangue - Production of new insulation materials. However, the new material is mainly used in steel housing, high-rise buildings in the material has not been widely used. For the higher rate of urbanization in terms of Taiyuan, the insulation material can be replicated is still unknown. Moreover, steel houses in rural areas to promote and villagers received, there is a relatively long process. Ways Fujian and other places began to use the abandoned coal gangue resources to produce methanol, inorganic fibers, architectural decorative glass-ceramics, the main material aluminosilicate based cementitious materials, coal burning calcined alumina extraction of high-value products ...... Waste Utilization is gradually being developed, although the market prospects of its subsidiary product is not yet clear.
Accelerate rural and urban cleaning, also Qingxu, the ancient post of many villages in true colors, the gangue this solid waste is increasingly converted into building materials, chemicals and other available resources, should be incorporated into the city as soon as possible, the county government agenda, and the introduction of appropriate fiscal policies. How to change the resource curse, to eliminate as soon as possible escape or leaching of sulphide gangue adverse effects on the atmosphere, farmland and water brought to gangue looking for a "future", is imminent.
